A trifocal lens provides three distinct viewing zones for which of the following?

Explanation:
Three distinct viewing zones are the hallmark of trifocal lenses. They’re designed so you look through different parts of the lens for different distances: the top portion for distance, the middle for intermediate tasks like computer work, and the bottom for near tasks such as reading. This integrated setup lets you switch focus without changing glasses. So, the statement that a trifocal lens provides three viewing zones is correct. The other options imply fewer zones or only one zone, which doesn’t describe trifocals.
